You specify to the "binToText" function that the maximum number of
characters the resulting string should be represented on is sizeof(ULONG) -
which I assume is 4 or whatever number of bytes your system represents
unsigned long on.
I guess the number stored in "board_id" is represented on more digits than
that, and it doesn't fit.
